Skylights can add a lot to a home. They are aesthetically pleasing and increase exposure to natural light. They create an illusion of space and make rooms seem larger than they are. Indoor plants that need a lot of sunlight can thrive more easily in a room with a skylight.

To install a skylight, a specialist cuts a hole into the roof and ceiling, fits the skylight into the new space, and seals it into place. Between the skylight price and the installation process, the average skylight installation costs between $800 and $2,500, with the average customer paying $1,500 for a medium-sized ventilated skylight with a vinyl frame, plastic coating, and flashing. At the lowest cost, expect to pay around $650 for a small, fixed skylight with a vinyl frame. At the highest cost, you can install a large, solar-operated ventilated skylight with a wood frame for $3,800.

Skylight Cost by Types

Like windows, you can find different skylights, each with varying attributes that make one or another a better fit for your home. Most skylights have a starting price point similar regardless of the type, but some skylights may offer more options than others. There are three main categories of skylight: tubular, fixed, and ventilated.

Skylight Cost Chart

Skylight Cost Chart

Type of SkylightAverage Costs (Material Only)
Tubular$150 - $600
Fixed$150 - $1,000
Ventilated$150 - $2,000

Tubular Skylights Cost

These are not skylights in the traditional sense, but they bring extra sunlight into the home. From the inside of the home, tubular skylights look just like brighter versions of ordinary lights. Tubular skylights get their light from tubes that are installed on the roof. These tubes direct light into the house via reflective piping.

Tubular skylights are inexpensive because they require fewer materials and less labor. The simplest tubular lights can be installed in two hours. However, tubular skylights do not provide a view of the sky, which is the primary draw of a skylight. They also do not work well for large spaces that require a lot of light. They are small, and unlike ordinary electric lights, they do not provide light after sundown. But they make a good choice for closets, bathrooms, and utility areas that do not get much use at night. By using sunlight instead of electricity for these spaces, homeowners save money on their electric bills. Tubular skylights cost between $150 and $600.

Fixed Skylights Prices

Fixed skylights are the simplest type and provide extra light to a room. They do not open or close in any way. Being a simple choice, they are good for first-time skylight buyers, and they are relatively inexpensive. Consider your home’s location before you buy a fixed skylight. Because they have no ventilation options, they can trap heat inside your home. That is not bad during the winter months, but if you live in an area that gets hot during the summer, you may want to consider a ventilated skylight instead. Fixed skylights average $150 to $1,000.

Ventilated Skylights

Ventilated skylights provide ventilation, allowing you to release any heat trapped underneath your skylight. A vented skylight can also let spring breezes into the house when the weather permits.

Vented skylights come in a few choices. Manual vented skylights open and close just like a regular window, which is why they are sometimes called tilt window skylights. The electric versions of vented skylights open and close via a remote control. There are even solar-powered vented skylights that use sunlight to recharge their batteries.

If you are thinking about a ventilated skylight, you have to weigh the pros and cons. First, vented skylights are more expensive than fixed skylights. Second, each variation comes with different factors that you should consider. For example, a tilt window skylight works best on lower ceilings that allow you to reach the vent. Electric skylights work at any height, but they require wiring installation, and you need to hire an electrician for that. Electricians charge between $40 and $120 per hour.

Ventilated skylights have a wide range of costs, from $150 to $2,000 with the most expensive being electric and solar-powered models. A manual vented skylight costs roughly $500. An electric version averages $1,400. The average solar-powered model, meanwhile, costs about $1,500.

Skylight Cost by Size

Not all skylights are available in every size, and not every size of skylight provides all the options. However, you can get a general idea of what your skylight costs based on the size. With options like frame material, glass, and operation, each size has a wide range of costs.

Skylight Prices Chart

Skylight Prices Chart

Skylight SizeAverage Cost Range (Material Only)
25” x 25”$160 - $1,430
25” x 33”$190 - $1,430
25” x 41”$215 - $1,450
33” x 33”$230 - $1,500
25” x 57”$299 - $1,600
33” x 49”$330 - $1,630
49” x 49”$365 - $1,900
33” x 57”$430 - $1,700

Skylight Prices by Framing Material

Skylights come in vinyl, wood, metal, and a mixture of materials. Each material has a different price point and maintenance needs, which may make one a better fit for your home:

Skylight Material Prices

Skylight Material Prices

Framing MaterialAverage Costs (Material Only)
Vinyl$160 - $1,500
Metal$200 - $2,500
Wood$300 - $3,500

Vinyl Skylights

Vinyl is a common choice because it seals moisture well and lasts a long time. They are easy to produce and locate, being the same material that many window makers use for their products. Vinyl can crack in cold climates and warp in hot climates, and it is difficult to paint if it becomes discolored. Vinyl comes in a range of types and sizes, with a price range of $160 to $1,500.

Metal Skylights

Metal works for those who want a contemporary look, but metal also heats quickly, adding a level of discomfort to homes with hot summers. Metal skylights can come with a wood look, or they can be vinyl-wrapped for a cooler exterior. They are lower in maintenance than wood and last longer than vinyl. They are a good option to mix longevity and style. They have a cost range of $200 to $2,500 on average.

Wood Skylights

Wood is a good material for helping insulate your skylight. It also has a natural beauty and grain that is difficult to reproduce. Wood skylights have higher maintenance and tend to cost more. The wood needs to be painted or stained regularly, and it should be checked for moisture problems and rot regularly to help prevent issues. They have a cost range of $300 to $3,500 on average.

Skylight Pricing by Style

Skylights come in two general installation styles - curb- mounted and deck-mounted. Curb-mounted skylights are mounted on top of a frame, while deck-mounted skylights are installed flush with your roof. Some people prefer the curb appeal of deck-mounted skylights because curb-mounted skylights are more noticeable from the street. They have similar costs for materials, although a deck-mounted skylight takes longer and costs more to install.

Skylight Pricing Chart

Skylight Pricing Chart

Skylight StyleAverage Cost (Material Only)
Curb Mount$250 - $1,500
Deck Mount$280 - $2,000

Curb-Mounted Skylights

Curb-mounted skylights sit above the roofline. This makes them more visible from the street but provides more space inside, which can be a desired look for some interiors. Curb-mounted skylights are easier to install and go up faster in new and replacement installations than deck-mounted. They cost between $250 and $1,500, depending on the material and size.

Deck-Mounted Skylights

Deck-mounted skylights are flush with your roof, rather than sitting above it. This means that it needs to be framed inside your roof, and it is less visible from the street. It also means it has less of a visible frame inside, with a little less space. This installation takes longer and is more costly for new and replacement installations. Expect costs between $280 and $2,000 on average, depending on the size and material.

Skylight Price by Shape

While most skylights are either rectangular or square, they can come in other shapes. The shape impacts the cost because it influences the skylight you purchase. Each shape has a range of costs, depending on the mounting style, frame material, and screen.

Skylight Shape Prices

Skylight Shape Prices

Skylight ShapeAverage Cost Range (Material Only)
Oval$150 - $1,100
Circular$150 - $1,100
Triangular/Pyramid$150 - $2,000
Square$160 - $1,500
Rectangular$190 - $2,000

Oval Skylight

If you opt for a solar tube, one option is an oval-shaped skylight. Oval skylights are a flat oval on the interior, but the exterior has a dome or bubble on top. They are almost always made of plastic and cost $150 to $1,100 on average.

Circular Skylight

Circular skylights are identical to oval skylights in their overall appearance, installation, and material. They just have a round, circular shape rather than an oval one. They have a highly visible dome on your roof and are made of plastic. They cost between $150 and $1,100 on average.

Triangular Skylight

Triangular or pyramid skylights are raised skylights that form a pyramid on your roof. They can be made up of multiple panes of glass or plastic to let light in and make an architectural statement. They have square or rectangular bases, leading up to the point on top. They have several styles, material options, and sizes, leading to a price range of $150 to $2,000.

Square Skylight

Square skylights are a good option for smaller rooms, where you want to add some light but do not have the ceiling space for a larger window. Square skylights come in several sizes, materials, and installation options, making them versatile. They cost $160 and $1,500.

Rectangular Skylight

Rectangular skylights are one of the most common styles, especially for larger rooms and homes. They can have many different configurations, such as longer and thinner or shorter and squatter. They also come in several sizes, materials, and installation styles. They have a cost range of $190 to $2,000.

Skylight Costs by Screen Material

The main skylight screen can be made of different materials, mainly glass or plastic. Consider several things when choosing between different kinds of glass and plastic screens. You need to think about the glass slope. While some skylights are flat, there are also domes and pyramids to consider. These have roughly the same costs for the glass and installation. This assumes the same materials are used, which is almost always acrylic because it allows them to take on rounded shapes.

Skylight Costs Chart

Skylight Material Costs Chart

Screen TypeAverage Costs
Acrylic Plastic$150-$500
Tempered Glass$150-$1,300
Double-Pane Glass$300-$3,500

Acrylic Plastic

Acrylic plastic or plexiglass is a highly durable material that makes a great pane for skylights. It is frequently used to make dome and pyramid skylights and can also be made in flat panels. It is shatter and crack-resistant and filters out UV light. This material costs $150 to $500 on average.

Skylight Tempered Glass

Tempered glass is another good, durable option for skylights for those who want true glass clarity. Tempered glass is stronger and less likely to shatter if cracked. So if you live in an area that sees occasional hail, it is a good option. This glass costs $150 to $1,300.

Double-Pane Skylight

You want double-pane glass if you want to improve your skylight’s energy efficiency. Having two panes of glass allows air to be trapped between them, stopping thermal transfer. This makes a good option for anyone who wants to save on energy bills while having a skylight. This glass costs $300 to $3,500.

Skylight Prices by Brand

There are not many skylight brand options because a few major brands dominate the market. Each brand has its characteristics and materials to consider as well as price ranges:

Skylight Brand Prices

Skylight Brand Prices

Skylight BrandAverage Cost Range (Material Only)
Sun-Tek$125 - $1,000
Velux$350 - $2,000
Fakro$500 - $3,000

Sun-Tek Skylights Prices

Sun-Tek is a good choice for very basic, no-frills skylights. They have a range of sizes and glass options, including some domed skylights. They are readily available and easy to install. You can find them in sizes and materials that match many homes. They cost $125 to $1,000.

Velux Skylights Prices

The most common brand for glass skylights is Velux, often the go-to source for skylight needs. Velux is the top-rated brand with a reputation for quality products. They have a wide range of options, including tubes, acrylic options, wood options, and curb-mount and deck-mount styles. The average costs are between $350 and $2,000 for most skylights.

Fakro Skylights Prices

Fakro is the other major skylight brand that you see many options from. While it does not dominate as much of the market as Velux does, Fakro makes sturdy, reliable, quality products. They have many styles, including several glass types and styles for both curb-mount and deck-mount skylights. They cost between $500 and $3,000.

Skylight Installation Cost

The skylight installation process has an exterior phase and an interior phase. During the exterior phase, the installer measures and cuts a hole in the roof. Then, the installer fits the skylight into the hole and installs any added exterior components, such as flashing. During the interior phase, the installer fits the skylight’s interior pieces into place. The amount of time the installer needs for this process depends on the project’s complexity, the roof shape and slope, and the roofing tiles you have. A project with an average roof slope, small skylight, and no complications can take four hours from start to finish. A larger or more labor-intensive skylight installation takes closer to three days.

The labor cost for this time depends on the company you hire. Skylights can be installed by roofers, carpenters, and window specialists, but not all these companies provide skylight installation. Among those who install skylights, roofers charge $45-$75 per hour, carpenters charge about $70 per hour, and window installers charge about $40-$50 per hour.

Factors Affecting the Cost of Installing a Skylight

Several factors determine the cost of your skylight installation. First, skylights come in different sizes. The bigger the skylight, the more it costs. For example, a quality skylight at 22½”x22½” costs roughly $170. A comparable skylight at 46½”x46½” costs closer to $600.

After size, consider flashing as a possible cost increase. Flashing seals away condensation, and depending on your skylight’s location, it may need that flashing. Some skylights come pre-equipped with flashing, but others do not.

Next, the mount type impacts the skylight pricing. There are two main ways to mount a skylight: curb (mounted) or deck (flush). Some skylights can be installed flush with your roof. Those are called flush skylights or deck skylights. Alternatively, curb skylights are built on top of a frame or mount. Curb and deck skylights have comparable prices, but the real cost consideration comes from the installation. It is easier for installers to add a mounted skylight to an existing roof. For a deck skylight, you pay more in labor costs. If you have metal or tile roofing, that drives up your labor costs because this job is difficult.

Skylight Replacement Cost

Skylight replacements cost more than new installations. The old skylight must be removed, which costs $50 to $200, depending on how it was installed and the type of roofing shingles and flashing. If you are installing the same size and shape skylight, your costs from this point are similar to the costs of a new installation. When changing the size and shape, you have additional labor costs. Installation of a replacement can take a few hours to a few days, depending on the installation type. So while a new installation has an average cost range of $800 - $2,500, a replacement could cost between $850 and $5,000, depending on the job’s difficulty.

Skylight Energy Efficiency

When considering skylights, think about your energy-efficiency options. In the right circumstances, skylights save on energy. Since heat rises, vented skylights can give summer heat a way to escape when it gets stuck indoors. Furthermore, the light provided by a skylight can bring more heat into the home during the winter.

If you wonder if there is any way to maximize winter efficiency while minimizing the summer heat production, the answer is yes. First, look for energy-efficient products. Start by looking for a seal of approval from either Energy Star or the National Fenestration Rating Council (NFRC). Energy Star is concerned with energy-efficient options for all kinds of home products, and the NFRC focuses specifically on windows and similar products.

You can also improve your skylight’s energy efficiency by placing it in the right location. For example, a north-facing skylight does not invite much heat into your house during sunrises and sunsets. Additionally, it is essential that your skylight has proper insulation and is installed with a tight seal to avoid letting air escape from the house. You might consider certain enhancements that make your skylight more energy-efficient, such as solar-powered skylights. There are also options for tinting and blinds. Blinds add between $200 and $400 to the project. Low-E coating protects your skylight and your home from UV light, making it a good choice for acrylic skylights. This coating usually adds about $15 per sq.ft. of window space.

Skylight Size

Think about the skylight size. First, measure the size of the skylight you want installed.

Most experts recommend 1 sq.ft. of skylight per 20 feet of flooring. If the room has windows, the skylight should take up no more than 5% of the flooring space. If the room does not have windows or has few windows, it should take up no more than 15%.

Typical sizes for a rectangular skylight span from 14 inches up to 72 inches. A tubular skylight is usually no larger than 22 inches in diameter. The cost for a 14-inch fixed rectangular skylight installed with no customizations is $650 with installation. A 72-inch skylight of the same type would be about $1,000.

Flat Roof Skylight Prices

While it is recommended that skylights not be installed on flat roofs due to the risk of leaks, new technologies have made it easier to install skylights on flat roofs. Most skylights for flat roofs have a slight dome to the surface. This helps prevent breakage and leaks. The skylights are installed in a curb-mount style and can be fixed or open wide to provide rooftop access. They have starting costs similar to most acrylic skylights, with costs ranging from $150 to $1,000 for the materials. The increase in costs for the extra material is necessary for the domes. Installation is nearly identical to a curb-mount install on a pitched roof, so total costs are similar - between $650 and $2,000, depending on the model.

Skylight Maintenance

Skylight maintenance is often similar to window maintenance but involves your roof. Ensure that the flashing and shingles around the skylight are in good condition to prevent leaks. Also, make sure that the frame is in good condition and that you apply caulk and paint and stain wood frames as needed. Vinyl and metal skylights have little maintenance beyond caulking and keeping the roof in good condition to prevent leaks.

Enhancement and Improvement Costs

Electric Shades

One thing you can do to enhance your skylight is to add electric shades controlled with a remote. These shades can be lowered to block light during the hottest parts of the day. They cost about $400.

Impact Glazing

Many skylights are made with impact-resistant glass or acrylic screens, which are impact-resistant. The cost of having impact glazing is between $150 and $2,500, with the skylight’s shape and style making up the bulk of the cost.

Insect Screens

If your skylights are operational, install insect screens to keep pests out. These cost $10 to $50 each, but you may need to have a custom screen made if you have an oddly sized skylight.

Skylight Tinting

Skylight tinting can help prevent some of the glare that comes with an overhead window. Tinting for skylights costs between $8 and $9 a square foot.

Additional Considerations and Costs

  • Permits. Many cities require property owners to get a permit before they can have a skylight installed. Permit fees start at around $50, but they may go up, depending on the project’s complexity.
  • Cleanup. The cleanup process should be included in the labor costs. Most installers lay plastic sheeting down before they start doing interior work on skylights to protect your home from dust. If you want to hire a cleanup service instead, a house cleaning service may provide what you need for $100-$150.
  • Insulation and waterproofing. Flashing can insulate your skylight and protect your home from water. Most skylights come with flashing included in the price.
  • Leakage. A skylight does not leak when properly installed. However, if you have a particularly old skylight or the glass gets broken, you may notice leakage. In that case, have your skylight repaired.
  • Skylight vs solar tube lighting. If you want a view of the sky and more light exposure, then a skylight makes an excellent choice. However, if your primary goal is using solar lights to save electricity, consider choosing a solar tube instead. This directs natural light into the home through a reflective tubing system. Solar tubes cost between $100 - $600.
  • Placement. Put thought into your skylight’s placement. Talk to your installer about the ideal placement. The installer offers advice based on your roof slope, skylight size, and more.
  • Path of the sun. Light brings heat, so think about the path of the sun. Skylights installed in high-sun areas bring in more heat than a regular window.
  • Belongings. Move furniture, potted plants, and other belongings out of harm’s way during the installation process.


  • How much does it cost to have a skylight installed?

Installing a medium-sized ventilated skylight with vinyl frame, plastic coating, flashing included, and a 1-2 day installation process averages $1,500.

  • Do roofers install skylights?

Some roofers do install skylights, but not all of them do. Look for roofers, carpenters, and window and door specialists when looking for someone to install your skylight. Roofers charge between $45 and $75 per hour.

  • Do skylights add value to your home?

Skylights can add value to your home, especially when buyers are interested in this feature. However, it does depend on the housing market at the time when you decide to sell your house.

  • Do skylights make a difference?

In terms of adding natural light to a home, skylights make a big difference, especially if they face east or west. Because they’re installed into roofs, skylights allow in more sunlight than regular windows.

  • Do all skylights leak?

No, but some skylights do leak eventually due to age and/or damage. Flashing can prevent skylight leakage. Additionally, some skylights gather condensation that eventually evaporates without any issues. Pay attention to your skylight for signs of leakage as it ages.

  • Do skylights make a room hot?

They can make a room hot. You can reduce the potential heat by having blinds installed or by installing your skylight in a low-sun area.

  • How much does it cost to put skylights on a roof?

This has a wide range of costs, depending on the skylight, shingles, and roof type. Expect to pay between $800 and $2,000.
